The Ravens' no-huddle offense became the buzz of the NFL when it helped Baltimore produce 37 points in the season opener. Then it disappeared Sunday as the Ravens could only manage two long field goals in the second half.

While the numbers show the Ravens are better when running the no-huddle, you don't need statistics to see Joe Flacco is more comfortable in it. So why did the Ravens get away from it in Week 2? As in real estate, it's all about location, location, location.

It's easy to shout out plays at the line of scrimmage in the friendly surroundings of M&T Bank Stadium. When Baltimore has to deal with the screaming opposing fans, like Sunday at Philadelphia, the Ravens decided huddling up was the best way to communicate the plays.

“Crowd noise is always a factor in a stadium like that, especially when the game got close," coach John Harbaugh said Monday.

According to the official NFL stats, the Ravens were in the no-huddle 22 times when they played at home. Baltimore only ran the no-huddle six times in Philadelphia, including twice in a stagnant second half.

Harbaugh, though, believes the Ravens didn't get away from the concepts of the no-huddle in a 24-23 loss to the Eagles.

"I don’t feel like it was tabled; we were still in it to some extent," he said. "Our pace was what we wanted it to be in terms of if we were more in run-pass. We were at the line calling plays quite a bit, and we were in huddle a little bit.”

The Ravens return home to play the New England Patriots on Sunday. It's a rematch of the AFC championship game. It's also the likely return of the Ravens' no-huddle offense.
